Using a wireless bottomhole pressure (BHP)/temperature telemetry-acquisition system in artificial-lift operations can improve efficiency and optimize fluid producing rates. Installed in the producing well, close to the perforations, the tool measures and transmits the producing BHP's and temperatures to the surface for instantaneous control of the pumping motor speed. This ensures the lowest possible fluid-level backpressures, allowing the highest possible fluid entry into the wellbore. The telemetry tool is deployed with standard slickline equipment and is installed inside a well in a manner similar to ordinary pressure-recording tools. Tool features include no moving parts, no wireline to the surface, real-time measurement of bottomhole data, and slickline re-trievability. Future versions of the acquisi-tion-system tool will improve operating efficiency by providing temperature moni-toring and control of perforation scaling, tu-bular waxing, and tubular hydrating plugs. The tool will provide data necessary to create diagnostically predictive inflow-perfor-mance-rate curves through monitoring of reservoir inflow rates. The tool will also pro-vide early warning of water encroachment or lensing through fluid resistivity monitoring.
